The present invention is directed to an improvement upon that of my copending application Serial No. 122,378, filed January 26, 193'?, issued on October 19, 1937, under Patent No. 2,096,591.

Withthe foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spiritof the invention.

The invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a side elevation of a beer drawing system with parts in cross section.

vFigure 2 is a cross section on a larger scale taken on line 2 2 of Figure 1, and showing the tube within a tube construction of this section of the device.

In the drawing bar I is shown provided with a spigot 2. A cooling tank 3 equipped with an appropriate refrigerating coil (not shown) therein is shown positioned within the bar I and has a `vertical cooling chamber positioned below it which comprises a tube 5 having a smaller tube 6 positioned within it, the jacket between the tubes 5 and Gbeing closed at the top by a closure 1, and at the bottom by a closure 8. A pipe 9 communicates with said jacket at the side of the tube 5 near its upper end and extends upward to,

near the top of the cooling tank 3. The lower end of the tube 6 extends below the closure 8 union III.

and terminates in an out-turned iiange forming a Positioned below the union I0 and forming'a part thereof, there is a manifold with a`plurality of outlets and inlets for the circulation of the cooling agent to a number of beer kegs. Thismanifold comprises a tube-like member I2 having a plurality of taps I3 therein. A tube I4 ,ofsmaller-diameterl positioned within the tube I2 has a ,passage opening from it to the union I0, 'thus' connecting it directly with the tube 6.

A plurality'fof taps I5 extend from thetube Il out .through the sides of the tube I2. These taps I3 and I5 are adapted to circulate the cooling agent 'through a number of' beer kegs. A keg I 6, having its 'eenling coil (not-shown) built therein,- is shown connected by meansof flexible hose I1 to apair of' taps- 'I'3- and I5. A tap i8 at one end of the manifold connectsa circulating. pump I9 to tap II near the lowerend o f tube 5.

At the opposite end of'the manifold there ls provided an extra-pair 'of taps I3 and. I5 which provide connections for cooling a plurality of additional beer kegs 20 connected in series.l Positioned in the center 'of the vertical cooling chamber `4 and extending upwardly 'into the cooling 1 tank 3 and outwardly to the spigot 2,"vthere is a pipe 2l which provides passageway for `the-beer. The .lower'end of this pipe or brew line 2I'extends downwardly through lthe manifold and terminates in a head 22 having a plurality-of taps 23 One of these taps 23 is shown connected by means of .a exible tube 24 to the beer connection of the keg I6 and the othertaps 23 are similarly connected to other lkegs.

cooling agent.

It will be apparent that whena plurality of I kegs of the same beer'are connected in parallel Arrows on the drawing indicate the circulation of the 33 the jacket I2'-I'4 of the manifold and thence by way of tap I8 back to the pump. In this manner the contents of the keg I6 are maintained at all times at drinking temperature. The single beer pipe 2| communicating by way of head 22 to the various kegs on the line in parallel, itis apparent that when the spigot 2 is opened, beer will 'be drawn at the same time from each and every keg on the line. This arrangement is feasible and practical where one type of beer is to be served. Therefore it is unnecessary for the bartender to connect fresh kegs to the cooling line except at the rather long intervals that all of the kegs on the line shall have been drained. The arrangement of an extra supply of kegs untapped and in reserve to have cooling fluid circulated therethrough in sexies from the manifold is advantageous in assuring an emerger/icy supply of brew pending replacement of tli empty kegs with fresh ones. Byreason of/'t e higher linear resistance of the line connecting the kegs in series, which is operated at the same pressure as the individual kegs connected in parallel, the water will course at much slower rate through said kegs on reserve and will not keep .them at drinking temperature but will yet maintain them at a temperature suiiiciently low to guard against spoilage. Economy ofequipment and refrigeration, is thus effected.

What I claim is:

1. vA brew cooling and dispensing installation comprising a plurality of kegs having cooling conduits therein, a` single dispensing faucet remote from the. kegs, an elongated brew line extending from all of said kegs in parallel to said faucet, a conduit extending lengthwise of said brew line substantially the entire length of the latter and in heat exchange relation therewith and propulsion means communicating with the cooling conduits of said kegs in parallel and with the conduit along the brew line and serving to circulate cooling liquid through all of said conduits.
